Pro-Lok ELP-120 6″ x 1-3/4″ T-Style Latch Protector

Outswing is what the ELP-120 is for. The steel T-style guard covers the gap at the latch on an out-opening door, where the latch and strike are exposed from the outside, and it resists tools used to spread the door away from the frame. On an inswing door the latch edge is already protected by the stop, so a guard like this is not what you need there.

Both. The ELP-120 is stated compatible with deadbolts and with lock sets, so it covers a single-cylinder deadbolt strike or the latch of a knob or lever set. The T shape is what makes that work, the wider head sits across the strike area and the leg runs down the door edge. If you have a deadbolt above a separate latch, measure the spread between them against the 6 inch length before you commit.

On narrow aluminum stile doors, look at the guards built for that opening instead. The Don-Jo GLP-307 and LP-307 are both 2-5/8 by 7 inches for aluminum entrance doors, and the Don-Jo NELP-207 is 3-1/2 by 6-1/2 inches in 12-gauge steel for the same application, all out-swing. The ELP-120 is a general purpose 6 inch T guard, and on a narrow stile the head of the T can run past the available flat face.

The Pro-Lok ELP-120 is a 6 inch steel T strike latch protector for out-opening doors, compatible with deadbolts and lock sets, and it comes in aluminum and brass finishes. The Don-Jo LP-307 is a latch protector for aluminum storefront entrance doors, 2-5/8 inch by 7 inch in 12-gauge steel, for out swing applications. The LP-307 is the taller, narrower storefront plate; the ELP-120 is the wider T-shaped guard that also blocks attempts to spread the door from the frame.

A door with an exit device usually calls for a panic guard, which is a longer plate covering the device latch area. The Trimco PG8000 Series covers panic and latch guards for that purpose. The Pro-Lok ELP-120 is a 6 inch T strike latch protector for out-opening doors, compatible with deadbolts and lock sets, so it suits cylindrical and deadbolt latches rather than a panic device latch.

For an aluminum storefront stile, the Don-Jo LP-307 is built for that opening: it is a latch protector for aluminum storefront entrance doors, 2-5/8 inch by 7 inch in 12-gauge steel, out swing. The Don-Jo GLP-307 covers aluminum entrance doors at the same 2-5/8 inch by 7 inch out swing size. The Pro-Lok ELP-120 is a 6 inch T strike protector whose wider T covers the strike side, which narrow storefront stiles often cannot accept.

The Don-Jo NELP-207 is a shorter plate: 3-1/2 inch by 6.5 inch in 12-gauge steel for aluminum entrance doors, out swing. The Pro-Lok ELP-120 measures 6 inch by 1-13/16 inch as a T strike protector for out-opening doors. Measure the clear flat area on the strike side before choosing, since the NELP-207 is wider across the door face while the ELP-120 is longer along the edge.

Neither is an in-swing solution in the usual sense. The Don-Jo GLP-307 is an out swing latch protector for aluminum entrance doors, 2-5/8 inch by 7 inch. The Pro-Lok ELP-120 is described as a T strike protector that obstructs and blocks access for in or out swinging doors and resists tampering by devices used to spread the door from the frame, with the size given as 6 inch by 1-13/16 inch. If the door swings in, the ELP-120 T strike form is the one addressing that condition.

Typically it takes two. The Pro-Lok ELP-120 is a commercial-rated 6 inch T strike protector for out-opening doors, compatible with deadbolts and lock sets, and rated for residential, commercial and industrial use. For the aluminum storefront openings, the Don-Jo NELP-207 at 3-1/2 inch by 6.5 inch or the Don-Jo LP-307 at 2-5/8 inch by 7 inch are made for aluminum entrance doors. Doors carrying exit devices fall to the Trimco PG8000 Series panic and latch guards.

Two, aluminum and brass. That is the whole choice, so pick the one that reads closest to the existing hardware on the opening. Property managers standardizing a building usually run aluminum against aluminum storefront and painted hollow metal, brass against brass or bronze lever and deadbolt trim.

It carries a commercial designation and the product data covers residential, commercial and industrial use, so the same guard goes on an apartment unit door, a back-of-house exit at a restaurant, or a warehouse man door. It is a mechanical steel cover, there is nothing in it that changes by building type.
